Description

Technical Field

[0001] The present invention relates to the technical field of water environment sampling, and particularly to an energy-saving and environment-friendly portable water environment sampling device. Background Art

[0002] For the water quality environment, it is necessary to sample and detect the river water irregularly to know the water quality of the water area, and then arrange the subsequent work.

[0003] When sampling river water, an empty container is filled and collected at multiple places in the river. Although this sampling method and tool are simple, only the river water at one level can be sampled at a time, and multiple samplings are required for comparison. After sampling, by manually pulling the wire rope, during the lifting process, the shaking of the container will not only cause the sample to spill, but also because the sampling container is lifted from the bottom to the water surface, the upper water body in the river water will enter the sampling container, affecting the accuracy of the detection results. Summary of the Invention

[0010] Preferably, the energy storage component includes a piston plate, a vertical rod, a handle and two first springs. The piston plate is slidably connected to the water storage tank of the sampler. The bottom end of the vertical rod is fixedly connected to the piston plate. The top end of the vertical rod penetrates through the upper surface of the water storage tank and is fixedly connected to the handle. The vertical rod is slidably matched with the top of the water storage tank. The bottom end of the first spring is fixedly connected to the upper surface of the piston plate. The top end of the first spring is fixedly connected to the inner top wall of the water storage tank.

[0011] Preferably, the limiting component includes a fixed seat, a rectangular rod, a positioning block, a second spring and a rectangular frame. The bottom end of the fixed seat is fixedly connected to the upper surface of the water storage tank of the sampler. One end of the rectangular rod is fixedly connected to the positioning block.

The other end of the rectangular rod penetrates through the fixed seat and is fixedly connected to the rectangular frame. The rectangular rod is slidably connected to the fixed seat. The second spring is sleeved on the outer surface of the rectangular rod.

[0012] Preferably, the positioning block is of a wedge-shaped structure. A positioning groove is formed at the position where the upper side of the vertical rod is clamped with the positioning block. The positioning block is adapted to the positioning groove. A through hole cooperating with the positioning block is formed in the lower side of the vertical rod. The size of the through hole is larger than that of the positioning block.

[0013] Preferably, the control component includes a telescopic rod, a limiting block and a third spring.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The device of the present invention is slowly placed into the river water and supported by the third spring, so that the conical block is away from the rectangular frame. When the specified depth is reached, the wire rope is pulled upward once, and the wire rope drives the pull ring and the sliding rod to move upward. During the movement of the sliding rod, the limiting block and the conical block can be driven to move. Due to inertia, the conical block moves upward relative to the box body. At this time, the conical block squeezes a rectangular frame to move towards the middle of the box body. During the movement of the rectangular frame, the rectangular rod and the positioning block can be driven to move. During the movement of the positioning block, the second spring can be compressed and separated from the positioning groove on the vertical rod. At this time, the energy storage component resets to form a negative pressure at the bottom of the water storage tank. At this time, the water flow enters the water storage tank from the water pipe, so that automatic water intake can be realized without using electric energy, which is more energy-saving and environmentally friendly.

[0017] 2. By setting the limiting components on the sampler at different heights in the present invention, when the water storage tank is full of water, the vertical rod moves to the upper part. At this time, the positioning block enters the through hole under the restoring force of the second spring, and the rectangular frame is away from the conical block on the limiting block. Therefore, when the device continues to dive, it can sample the next water storage tank, and can sample the river water at multiple levels at one time, which is more convenient to use.

[0018] 3. In the present invention, sampling is carried out through the water storage tank. When the limiting component releases the limit on the energy storage component, at this time, the piston plate is driven to move upward in the water storage tank under the restoring force of the first spring. During the movement of the piston plate, a negative pressure is formed at the bottom of the water storage tank. At this time, the water flow enters the water storage tank from the water pipe, so that the sampled sample will not be spilled during the lifting process, and when it is lifted from the bottom to the water surface, the upper layer of water in the river water will not enter the water storage tank, improving the accuracy of the detection result.

At this time, water flows into the water storage tank 301 through the water pipe 302;

[0035] Preferably, the limiting assembly 7 includes a fixed seat 701, a rectangular rod 702, a positioning block 703, a second spring 704 and a rectangular frame 705.

[0036] Preferably, the positioning block 703 is of a wedge-shaped structure. At the position where the upper side of the vertical rod 602 is clamped with the positioning block 703, a positioning groove 706 is provided. The positioning block 703 is adapted to the positioning groove 706. A through hole 707 that cooperates with the positioning block 703 is provided at the lower side of the vertical rod 602, and the size of the through hole 707 is larger than that of the positioning block 703. The positioning block 703 is of a wedge-shaped structure, which can better limit the vertical rod 602 and reduce the frictional force between the positioning block 703 and the vertical rod 602. A positioning groove 706 is provided on one side of the vertical rod 602 close to the limiting component 7, and the positioning block 703 is adapted to the positioning groove 706. A through hole 707 is provided on the vertical rod 602, and the size of the through hole 707 is larger than that of the positioning block 703. During the movement of the rectangular frame 705, it can drive the rectangular rod 702 and the positioning block 703 to move. During the movement of the positioning block 703, it can compress the second spring 704 and disengage from the positioning groove 706 on the vertical rod 602. When the vertical rod 602 moves to the upper part, at this time, through the restoring force of the second spring 704, the positioning block 703 enters the through hole 707, and the rectangular frame 705 is away from the conical block 804 on the limiting block 802, so that the device can continue to dive to sample the next water storage tank 301;

[0037] Preferably, the control component 8 includes a telescopic rod 801, a limiting block 802 and a third spring 803. The bottom end of the telescopic rod 801 is fixedly connected to the inner bottom wall of the box body 1. The limiting block 802 is fixedly connected to the top end of the telescopic rod 801. A conical block 804 that cooperates with the rectangular frame 705 of the limiting component 7 is fixedly connected to the upper surface of the limiting block 802. The third spring 803 is sleeved on the outer surface of the telescopic rod 801. One end of the third spring 803 is fixedly connected to the lower surface of the limiting block 802, and the other end is fixedly connected to the middle of the inner bottom wall of the box body 1. A threaded hole 805 is provided on the upper surface of the limiting block 802, and the threaded hole 805 is adapted to the threaded column 502 of the connecting component 5.

[0038] Preferably, the telescopic rod 801 includes a fixed column 8011 and a movable column 8012. A cavity 8013 is provided inside the fixed column 8011. The bottom end of the movable column 8012 is located inside the cavity 8013 and is fixedly connected with a movable block 8014. The top end of the movable column 8012 penetrates through the upper surface of the fixed column 8011, and the movable column 8012 is slidably connected to the top of the fixed column 8011. During the movement of the sliding rod 501, it can drive the limiting block 802 and the conical block 804 to move. The conical block 804 moves upward relative to the box body 1. Since the heights of the multiple rectangular frames 705 are different, at this time, the conical block 804 can squeeze a rectangular frame 705 to move towards the middle of the box body 1.

[0039] The working principle of this embodiment is as follows:

[0040] When sampling, tie the wire rope to the pull ring 503, and then slowly lower the device into the river. It is supported by the third spring 803, so that the conical block 804 moves away from the rectangular frame 705. When reaching the specified depth, pull the wire rope upward and move it once. The wire rope can drive the pull ring 503 and the sliding rod 501 to move upward. During the movement of the sliding rod 501, it can drive the limiting block 802 and the conical block 804 to move. Due to inertia, the conical block 804 moves upward relative to the box body 1. Since the heights of the multiple rectangular frames 705 are different, the conical block 804 contacts one side of the inner ring of the rectangular frame 705 close to the middle of the box body 1. At this time, the conical block 804 squeezes the rectangular frame 705 to move towards the middle of the box body 1. During the movement of the rectangular frame 705, it can drive the rectangular rod 702 and the positioning block 703 to move. During the movement of the positioning block 703, it can compress the second spring 704 and disengage from the positioning groove 706 on the vertical rod 602. At this time, the piston plate 601 is driven upward in the water storage tank 301 by the restoring force of the first spring 604. During the movement of the piston plate 601, a negative pressure is formed at the bottom of the water storage tank 301. At this time, water flows into the water storage tank 301 from the water pipe 302. When the water storage tank 301 is full of water, the vertical rod 602 moves to the upper part. At this time, the through hole 707 reaches the height where the positioning block 703 is located. The positioning block 703 enters the through hole 707 by the restoring force of the second spring 704, so as to lock the vertical rod 602 of the water storage tank 301. At this time, the rectangular frame 705 also moves away from the conical block 804 on the limiting block 802. The device can continue to dive to sample the next water storage tank 301. Finally, after all the water storage tanks 301 are sampled, pull out the device, then rotate the sliding rod 501 to make the threaded column 502 at its bottom disengage from the threaded hole 805, and then open the box cover 2 and push down the handle 603 to make the sample flow out from the water pipe 302 to complete the sampling.
